| 20090075553 | MOTORIZED YO-YO - The invention is a yo-yo in which at least one of the yo-yo's sides includes a powered rotation system capable of maintaining the yo-yo's rotation when the yo-yo is sleeping at the end of its tether. The system functions by converting one of the yo-yo's sides into a motor, and in one embodiment includes a number of permanent magnets, an electromagnet, a sensor capable of detecting a magnet field, and a power source. Also disclosed is the use of a programmable controller to control the system. In another embodiment of the rotation system, a reflector, an energy emitter and a complementary sensor are employed to lead to an actuation of the electromagnet. | 03-19-2009 |
| 20100022159 | YO-YO HAVING A STRING-FORMED RESPONSE SYSTEM - The invention is an improved yo-yo that has two side units and a string-formed response system incorporated into each side unit. In its most basic form, the response system employs a string that is threaded through spaced-apart apertures in a side unit to form at least one tether engagement pad. The pad may be contacted by the yo-yo's tether in order to cause a return of the yo-yo to a user's hand. | 01-28-2010 |
| 20100317254 | YO-YO HAVING A PUSH-BUTTON LOCKING MECHANISM - The invention is a yo-yo that includes a user-actuable locking mechanism. The locking mechanism makes use of a laterally translatable assembly having a push button at each end and a center rotatable spool to which the yo-yo's tether is attached. Using the locking mechanism, a user can set the yo-yo so that the spool is either free to rotate, or must rotate with the yo-yo's sides. The yo-yo is also adapted for use with a spring-powered winder. | 12-16-2010 |
| 20110009029 | YO-YO HAVING QUICKLY-ADJUSTABLE RESPONSIVENESS - The invention is a yo-yo that includes movable shuttles that a user can quickly reposition between predetermined set points in order to adjust the yo-yo's responsiveness. Repositioning of the shuttles is accomplished via a cam surface connected to a rotatable dial. Preferably, the yo-yo also includes readily visible indicia associated with the shuttle's positioning apparatus so that a user can easily set and/or ascertain the yo-yo's responsiveness setting. | 01-13-2011 |

| 20100317255 | YO-YO HAVING TWIST-ON RELEASABLE RIMS AND YO-YO HAVING TWIST-ON GEAR-LOCKED BODIES - The invention is an improved yo-yo that features two side assemblies that sandwich a center axle onto which the yo-yo's tether may be secured. According to a first embodiment, each of the side assemblies preferably includes a releasable, disk-shaped rim piece. By replacing one set of replaceable rim pieces with another, a user can quickly and easily change the yo-yo's shape, look and/or functionality. To remove a rim piece, one first removes a lock ring that is secured to the rim piece and blocks a number of openings that lead to grooves in a center-located hub. Next, one employs a twisting movement of the rim piece to cause a number of tabs attached to the rim piece to slide in the hub's grooves until the tabs are aligned with the openings. The rim piece can then be disengaged from the yo-yo. | 12-16-2010 |
